In today's blog post we will look at the following remaining points: Bitcoin Origin Advantages Disadvantages Books related to it.. Future Assignment code : fun factor :) Conclusion You may wonder why the above list is beginning from "4", this is because we have covered the points: 1,2,3 previously... you can view them here  and here too :)  so without further ado, let's begin .... Bitcoin Origin When ever the word bitcoin comes into my mind, I used to think of the golden foil wrapped coin chocolates, but fortunately or unfortunately that used not to be the case. Actually One fine morning/evening/or on some other time of the day (2008), a person code named; Satoshi Nakamoto   ( People over the Internet are saying they don't know who is Satoshi Nakamoto, whether a person or some company.)  published a paper naming :   A Peer-to-Peer Electronic Cash System . I hope you have read that as I have attached the link to this paper in th...

Relational DB, ORM and ERP systems

When something is getting obsolete, we usually use to say it in Urdu as: Translation:That time has gone... With each passing second data is increasing and to make efficient use of that data we need to store it in some structured form. In past almost all the enterprises used to store data, in rows and columns on paper; like for attendance of staff members, there was a register in which name and corresponding status of attendance is marked. Bills, payment status, resource planning, human resource management, everything was (just) on papers. so yeah, that time has almost gone; when people used to store a lot of data on papers and in files.  Image Source But then technology grew up and paperwork is shifted on digital world. (But, there are still many companies relaying on paper work more than on computers!). So as mentioned above, the problem is; data is expanding. We need to deal with it, we need to manage it properly.  According to Quickbase article on datab...

In this blog post I will talk about: Software Design Patterns Open source platforms e.g. Joomla SEO (Search Engine Optimization) Swift vs Python React vs Angular vs vue.js Machine Learning and related learnings And Choosing Operating System.... Seems so strange, too many things with no visible links ....But wait! I have a solution to this problem, and the solution is in "telling a story" So let's begin John was a student of engineering, he was about to start his academic year for graduation. He wanted to go for software engineering as his major. He got admission in one of the most prestigious college of his state.  He was so passionate and optimistic about his field, he was good in programming and used to participate in every coding and programming contest.

Pintos : Series : Part 1 : Installation

-
Image
PintOS is an Operating system, but this is not a complete OS. There are many kernel level functions implemented but we need to modify it to implement it correctly. So, if you are taking OS course or interested in Operating Systems then you can follow my PintOS Series. As installation of PintOS is the most important and tedious task, so we need to do it first! Actually I have learnt about the installation steps from various sites, I will share their links side by side. What I grasped from there, I will compose it into this post. I know you might be thinking if the installation steps are already available on-line, then why am I writing them for you? The reason for this is that, when I installed PintOS, I found a lot of problems initially but then it worked. So, what I understood from my experience and from the sites, I will share that. I believe that if learning is done through mutual cooperation,  then this will benefit everyone . So, let's learn together.... First Mist...

Frameworks vs Libraries vs Services

-
Image
Framework, libraries and services are usually overlapped. In this blog post we'll see how are these things different from one another. First let's have a look at framework .. Let's tokenize this word. Framework is composed of two terms. one is frame and second is work. Frame is anything that you can put something into . Like a photo frame, you have some sort of skeleton in which you can put your photo. but the most important thing is that your photo must be of the size of the frame. If this isn't the case then you might need to buy some other frame or you might need to cut your photo from the borders, or the bottom or the sides or from anywhere. (in order to fit it into the frame) The second word is "work" what does work mean... Well according to Physics you are only doing work if and only if some force is applied and you cover displacement in the direction of applied force. But this is not the case with this work word. Here the work is nothing ...

In this blog post, we will be done with our Pintos Project #1 and this Pintos Series AlhumdullillAllah. so let's start... In the previous posts of this series, we have looked at the problem that is of busy waiting. To solve this problem I took help from code written by other people on Github,  so to learn it deeper you can get to look at this code, by Muhammad Zaheer  .  The basic modification is done in two files i.e. timer.c and thread.h;       ALARM CLOCK IMPLEMENTAIONS      ========================== Changes in timer.c:   - A global list of sleeping threads is created as: -static struct list sleep_list; Changes in thread.h:   - For keeping track of a sleeping thread when woken up, we declared: -int64_t sleep_time;   - When a thread calls timer_sleep(), it gets into the sleep list as: -struct list_elem sleep_list_elem Algorithms Used ...
